With a total of 2 patents, his work showcases innovative solutions that enhance the functionality and efficiency of various devices.
Latest Patents
Ohara's latest patents include an energization control device for electric motors and a rain drop detecting device. The energization control device is designed to prevent a rapid decrease of current flowing through the phase coils of an electric motor. It operates in three stages, utilizing soft/hard chopping energization control, 0-volt energization, and duty chopping energization control. This innovative approach ensures that the energization of the phase coil is managed effectively through a series of switching elements.
The rain drop detecting device features an oscillation element that generates ultrasonic waves on a plate member, such as a windshield. It includes a receiving element that detects the amplitude of these waves, along with an ultrasonic wave absorbing member. This design prevents inadvertent rain drop detection by controlling the ultrasonic wave's travel path, particularly in relation to the wiper's resting location.
